Andrea Barisani discovered that xzgv, a picture viewer for X with athumbnail-based selector, attempts to decode JPEG images within theCMYK/YCCK colour space incorrectly, which could lead to the executionof arbitrary code.

For the old stable distribution (woody) this problem has been fixed inversion 0.7-6woody3.

For the stable distribution (sarge) this problem has been fixed inversion 0.8-3sarge1.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your xzgv package.
